Vitor Matos feels Malick Yalcouye has progressed at Swansea City since he became the club's head coach in November.
The 19-year-old - currently on a season-long loan from Brighton & Hove Albion - endured a tough start to life in south Wales.
He started just five league matches under Alan Sheehan and did not feature in eight Championship games between late October and early December.
Yalcouye was also sent off in the Swans' 1-0 defeat by Queens Park Rangers under Sheehan on 22 October.
But he has shown signs of improvement under Matos of late and netted his first goal for the club in a 4-0 win over Sheffield Wednesday on 8 February.
"I think since I arrived he did steps forward. He came on from the bench (against Sheffield Wednesday) and he really affected the game I think that's always really good, not only him but other players as well," Matos said of Yalcouye.
Yalcouye has featured 25 times across all competitions so far for Swansea this season.
And Matos hopes he can keep adding to the versatile midfielder's development as he continues to adjust to the rigours of senior football.
"I think he's in the right way for his career," said Matos.
"I think how he's been doing in such a young age is good.
"He has a lot of talent inside of him and a lot of potential - it is up to me to find the best ways to use it."
